IMU failures

INS not calibrated.​

The offsets of one or all of the accelerometers are zero, therefore the accelerometers need to be calibrated.

Accels not healthy.​

One of the accelerometers is reporting that it is not working correctly, which is usually a symptom of a hardware failure.

Accels inconsistent.​

Accelerometers are reporting accelerations that differ by more than 1m/s/s. Accelerometers need to be re-calibrated or there may be a hardware failure.

Gyros not healthy.​

One of the gyros is reporting that it is not working correctly, which is usually a symptom of a hardware failure.

Gyro calibration failed.​

The gyro calibration failed to capture offsets.

  • Movement during calibration: Occurs when the Drone moves while calibrating (indicated by flashing red and blue lights).

  • Hardware failure: A less common cause but worth considering if the issue persists.

  • Unplug and reconnect the batteries.

  • Ensure no movement is introduced to the Drone during calibration.

Gyros inconsistent.​

Two gyroscopes are reporting rotation rates that differ by more than 20 degrees/s. Gyros need to be re-calibrated or there may be a hardware failure.

  • If the issue continues despite following these steps, it might indicate a hardware problem, and you should contact the manufacturer.
